A manakin typical of the Atlantic Rain Forest of south-east and south Brazil.
It measures between 10 and 11 cm with the two central tail feathers adding an additional 2 cm. It shows a sexual dimorphism typical of the family with the female mainly olive-green and grey.
The nest is a shallow cup with 2 to 3 eggs. It has a breeding display where a solitary male dances in front of the female and makes small jumps over the female from one small branch to another and back again - a bit like the act of sewing which gives the bird one of its regional names in Brazil.
The male emits some unusual sounds made with its tail feathers during the display flights. It sounds like a stick being run across a metal railing.
It is found in the lower and middle levels of humid forest and secondary woodland.
It is distributed in the Atlantic Rain Forest of Brazil from Boa Nova in Bahia to Santa Catarina.
